Abstract (en)
[origin: EP0534366A1] An acceleration sensor comprising a piezoelectric element (21) outputting an electric signal corresponding to acceleration applied, signal processing means (22-24) for processing a signal outputted from the piezoelectric element (21), AC signal outputting means (26) for generating an AC signal which is synchronized with the period of a timing signal externally inputted in response to the timing signal and applying the AC signal to the piezoelectric element (21), and a capacitor (25) connected between the AC signal outputting means (26) and the piezoelectric element (21). <IMAGE>
